The aim of this study was determination of relative frequency of
intestinal parasites in Hamadan military base in 1998.

406 persons of residents were selected randomly and their stool
samples were collected and related check lists were completed by referring
to the doors. The samples were examined by formol-ether method.

The detected results showed parasitic infection in 43.8% of residents
with the maximum percentage associated with Ascaris (42.7%) and Giardia
(21.9%) . Age group of 31-40 , primary school students and housewives had
more infection rates . Also small families (<3) showed the lowest rate of
infection.

According to this fact that the source of providing vegetables for the
military base and Hamadan city is the same , it seems that the sanitary
standards are at higher levels in the base .
